Abstract: Изобретение относится к хирургическому лечению послеоперационных вентральных грыж. Сводят мышечно-апоневротические слои краев раны с помощью спицевого устройства. При этом, если в процессе дозированного сведения краев раны внутрибрюшное давление не изменяется, то выполняют пластику местными тканями "встык" с дополнительным укреплением линии швов предварительно подготовленным аутодермальным сетчатым лоскутом, перфорированным в шахматном порядке. В случае повышения внутрибрюшного давления процесс сведения краев раны прекращают и к краям раневого дефекта пришивают предварительно подготовленный сплошной композиционный аутодермальный лоскут. Предварительная подготовка аутодермального лоскута включает следующие этапы: механическое удаление эпидермиса и подкожной клетчатки, выдержку лоскута и монофиламентных длительно не рассасывающихся синтетических нитей в течение 10-15 мин в охлажденном до 4-5 o С 5% растворе эпсилон-аминокапроновой кислоты, проведение нитей через толщу дермы лоскута параллельно или под углом друг к другу. В первом случае лоскут после этого перфорируют. Спицевое устройство удаляют на 5-6 день после операции в период стихания воспалительного процесса в области раны. Способ позволяет снизить число рецидивов и послеоперационных осложнений. 11 ил.
